Re: [Boost-users] identification of thread

There are 2 ways of identifying a thread. If you create a thread, you can path in the function object any members you like. It is also possible to pass some id (in case you create threads, you can assign them ids). Another way of identifying a thread, is doing so by its local storage. A pointer to a thread local storage will be different for each thread ;) Regards, Ovanes On Dec 12, 2007 7:56 PM, Scott Gifford wrote:

Could you please explain for beginner in thread-related business, how the thread is identified from itself? Can the program, that it the given thread, obtain its own number or an index of itself? I assume that there should be some enumeration such as numbering the main program by 0, next child thread by 1, etc.? And, in particular, is this number available from boost thread library?

Igor,

As far as I know, boost::thread does not provide any mechanism for this. However, you can use OS-specific system calls to get this information. For example, on my Unix system I use pthread_self() to get a thread ID.

boost::threads are very portable and so implement only the functionality that can be provided identically on all platforms. That's their greatest strength and their greatest weakness.

Good luck!
